This should be able to be done by using the ID name of the block. For example, iridium ore from IC2 has the name ID of “IC2:itemOreIridium”. In the config you would just put “itemOreIridium” and it should work. This is not tested with any mods though. I do not see why it would not work though. Give it a shot and let me know how it works for you. Thanks.
